eMoflon is a tool for building tools. It allows you to model software systems using a visual or a textual syntax, afterwards generating EMF-compliant Java code from your model.

Getting started with eMoflon

eMoflon is currently composed of two parts: eMoflon IDE Eclipse plugin Enterprise Architect addin (only required for visual syntax support) If you are completely new to eMoflon, we recommend working through our handbook first!

eMoflon is documented by our extensive handbook. Additionally, the eMoflon GitHub Wiki contains an FAQ site for specific questions. In the eMoflon Google group, we spread exciting eMoflon-related news (e.g., new releases). The file changelog.txt contains an overview of the changes introduced by each eMoflon version.


If you encounter problems, pleas consult our issue tracker or drop us a mail at contact(at)emoflon.org. Thanks!

A well-known problem is that the dependency from eMoflon to PlantUML is not resolved automatically. Please consult this post to solve the issue manually.

The current version of eMoflon is eMoflon 2.32.0. eMolfon is available via the Eclipse Marketplace. Just drag and drop the following button to your Eclipse instance.

Drag to your running Eclipse workspace.

Projects and institutions using eMoflon

The following is an overview of applications of eMoflon in industrial and scientific projects and for teaching purposes.

  • A case study using eMoflon for model based testing of Software Product Lines (MoSo-PoLiTe) is presented in this paper.
  • Subproject A1 of Multi-mechanism Adaptation for the Future Internet (Corporate Research Center of the DFG, 1053, MAKI)
  • Integrated Model-based Testing of Continuously Evolving Software Product Lines (DFG Priority Program 1593, IMoTEP, project website)
  • A solution for the Java Refactoring case study of the Transformation Tool Contest 2015. The case resources, the eMoflon solution (available for immediate execution in a Virtual Machine) as well as other solutions for a potential comparison can be found under http://www.transformation-tool-contest.eu/2015/solutions_refactoring.html.
